Systematic Parasitology (Syst Parasitol)

Publisher: LINK (Springer)

Journal description

Systematic Parasitology publishes papers on the systematics taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic) Monogenea Digenea Cestoda Acanthocephala Aspidogastrea Cestodaria Arthropoda (parasitic copepods hymenopterans mites ticks etc.) Protozoa (parasitic groups) and parasitic genera in other groups such as Mollusca Turbelleria etc. Systematic Parasitology publishes fully illustrated research papers brief communications and fully illustrated major revisions. In order to maintain high standards all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that in some cases this may cause problems for the authors but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa and the types will be preserved for posterity.

    ABSTRACT: Myxobolus balatonicus n. sp. was detected in the gill filaments of the common carp Cyprinus carpio L. collected in Lake Balaton, Hungary. Its oval plasmodia measuring 600-800 X 300-400 µm were located intravasally in the filamental arteries. The spores measured 11.2 ± 0.92 X 9.5 ± 0.41 X 7.4 ± 0.33 µm and had two equal polar capsules with six filamental turns. Both morphology and DNA sequence analysis revealed that M. balatonicus n. sp. is distinct from the ten species of Myxobolus Bütschli, 1882 described from the European common carp and the 21 species described from the Asian common carp subspecies. Phylogenetic analysis placed M. balatonicus n. sp. in a clade of gill-infecting myxobolids.

    ABSTRACT: Four new species of the genus Diolcogaster Ashmead, 1900 (Hymenoptera: Braconidae: Microgastrinae) are described and illustrated: Diolcogaster andamanensis n. sp. from the Andaman Islands, and D. duocolor n. sp., D. longistria n. sp. and D. solitarium n. sp. from mainland India. The solitary larval parasitoid D. solitarium was reared from Gatesclarkeana sp. (Lepidoptera: Tortricidae). A new combination, Diolcogaster tomentosae (Wilkinson, 1930) n. comb., is proposed for the Indian species Protomicroplitis tomentosae (Wilkinson, 1930) along with its redescription and documentation of the gregarious cocoons associated with the pyralid (Epipaschiinae) host feeding on Terminalia cattappa L.

    ABSTRACT: Previous studies from southern Japan reported larval stages of eight gnathiid isopod species parasitising coastal elasmobranchs. Since gnathiid larvae of these different species closely resembled each other, it was necessary to obtain specimens of free-living adult males for identification to the species level. This was achieved by allowing larvae of the final stage to moult into adult males. From these males, specimens of a species new to science were discovered and described here as Gnathia rufescens n. sp. The main differentiating characteristics of G. rufescens n. sp. are: (i) the apex of pleotelson is oval shaped; (ii) the dorsal sulcus is wide in the posterior part; and (iii) the article 3 of the pylopod is not reduced in the male. Additionally, this paper summarises the specific pigmentation patterns of third-stage larvae of the new species and eight previously described species. Furthermore, host records and host use by the gnathiids were summarised based on data from 158 hosts and over 4,500 gnathiid samples; these are discussed with a focus on host-specificity of the nine gnathiid species studied.

    ABSTRACT: A new species of Isospora Schneider, 1881 was discovered in the Mediterranean house gecko, Hemidactylus turcicus (Linnaeus) in Saudi Arabia. Both exogenous (sporulated oöcysts) and endogenous developmental stages (meronts, gamonts) were studied and measured. Sporulated oöcysts are spheroidal to slightly subspheroidal, 17-22 (18) µm wide, with a smooth, bi-layered oöcyst wall; micropyle, polar granule and oöcyst residuum are all absent. Sporocysts are ovoidal, 9-11 × 6-8 (10 × 7) µm, with both Stieda and sub-Stieda bodies, a dispersed granular sporocyst residuum, and four sporozoites. Endogenous stages develop extranuclearly in the cytoplasm of epithelial cells of the small intestine. Early uninucleate meronts are spheroidal, c.3-5 (4) µm wide. Multinucleated meronts are subspheroidal, 11-15 × 9-12 (13 × 10) µm, but mature meront and merozoites were not seen. Mature microgamonts, with up to 60 microgametes, are spheroidal, 11-15 (13) µm; macrogamonts are subspheroidal, with a prominent central nucleus, and measured 11-14 × 7-10 (12 × 8) µm.

    ABSTRACT: Three species of Procamallanus (Spirocamallanus) Baylis, 1923 (Camallanidae) (Nematoda: Camallanidae) were found in the digestive tract of freshwater fishes from the Okavango River, Botswana, i.e. P. (S.) daleneae (Boomker, 1993) from Synodontis vanderwaali Skelton & White (Mochokidae), P. (S.) spiralis Baylis, 1923 from Clarias stappersi Boulenger, C. theodorae Weber (both Clariidae) and Hepsetus odoe (Bloch) (Hepsetidae), and P. (S.) serranochromis n. sp. from Serranochromis macrocephalus (Boulenger) (type-host), S. angusticeps (Boulenger) and S. robustus (Günther) (all Cichlidae). All findings of the two previously known species represent new host records. The specimens were studied using both light and scanning electron microscopy. Spirocamallanus mazabukae Yeh, 1957 is considered a junior synonym of P. (S.) spiralis. A key to the species of Procamallanus (Spirocamallanus) parasitising fishes of continental Africa is provided.

    ABSTRACT: Parasitological dissections of fishes from the Okavango River, Botswana, revealed the presence of nematodes of the subgenus Procamallanus (Procamallanus) Baylis, 1923 in five fish species belonging to three different families. Based on light and scanning electron microscopical examinations, they proved to represent one previously known and one new species, i.e. P. (P.) laeviconchus (Wedl, 1861) from Synodontis nigromaculatus Boulenger, S. thamalakanensis Fowler (new host) (both Mochokidae) and Schilbe intermedius Rüppel (new host) (Schilbeidae), and P. (P.) pseudolaeviconchus n. sp. from Clarias stappersi Boulenger and C. theodorae Weber (both Clariidae). Specimens of the new species previously collected from Clarias gariepinus (Burchell) (type-host) in Egypt were also examined. Both of these nematode species are very similar, differing from each other mainly in the shape of the circumoral flange, which is conspicuously lobed in P. laeviconchus and unlobed in P. pseudolaeviconchus. Previously, these two species have been confused in the literature under the name P. laeviconchus. A key to Procamallanus (Procamallanus) spp. parasitising freshwater fishes in Africa, including Madagascar, is provided.

    ABSTRACT: A new genus and species of parasitic copepod, Gadilicola daviesi n. g., n. sp., is described based on material found on two different scaphopod host species collected in deep water (2,900-2,910 m) in the Rockall Trough, North East Atlantic. The copepods inhabit the posterior mantle cavity of their scaphopod hosts, Polyschides olivi (Sacchi) and Pulsellum lofotense (M. Sars). Both sexes are described. The female body comprises an unsegmented prosomal trunk and a 2-segmented urosome and is more modified than that of the smaller male which comprises a 4-segmented prosome and 3-segmented urosome. The pattern of sexual dimorphism of the appendages is characteristic of the poecilostomatoid families within the order Cyclopoida. The form of the antenna with the major claws on the second endopodal segment and with the third segment reduced and displaced laterally, is shared with the informal Teredicola-group of genera, but it lacks the distinctive, derived form of mandible shared by these genera. The new genus is treated as the type of a new monotypic family, the Gadilicolidae.

    ABSTRACT: A new species of hookworm, Uncinaria lyonsi n. sp., is described based on morphological studies of the nematodes collected by Dr. E. T. Lyons from the California sea lion Zalophus californianus (Lesson) on San Miguel Island, California, USA. The new species is morphologically similar to three other species of the genus Uncinaria Frölich, 1789 parasitising pinnipeds, U. lucasi Stiles, 1901, U. hamiltoni Baylis, 1933 and U. sanguinis Marcus, Higgins, Šlapeta & Gray, 2014, in the body dimensions, the structure of the buccal capsule, the shape and structure of the male caudal bursa and female genital system. Uncinaria lyonsi n. sp. is differentiated from U. lucasi by having longer spicules and gubernaculum, larger buccal capsule and more slender oesophagus. The new species differs from U. hamiltoni and U. sanguinis in having shorter spicules and narrower buccal capsule. The latter two species also occur in the Southern Hemisphere and are geographically separated from U. lyonsi n. sp. The present study confirms the existence of a host-specific species of Uncinaria in the California sea lion, previously revealed by molecular and biological investigations.

    ABSTRACT: A new species group nitidus is established within the genus Geckobia Mégnin, 1878 (Acariformes: Pterygosomatidae) based on an analysis of morphological characters of two newly described species from Chile: Geckobia nitidus n. sp. from Liolaemus nitidus (Wiegmann) and Geckobia zapallarensis n. sp. from Liolaemus zapallarensis Müller and Hellmich (Sauria: Liolaemidae). Mites of this new species group differ from species in the ovambica group in the presence of a movable cheliceral digit without basal spur, the absence of propodonotal shield and eyes, and in having shorter legs of the second pair, five setae on genua and femora I, four setae on genua and femora II, three setae on genua and femora III and two or three setae on genua and femora IV. Additionally, the third pterygosomatid species from Chile, Geckobia gerrhopygus n. sp. from Phyllodactylus gerrhopygus (Wiegmann) (Sauria: Phyllodactylidae) belonging to indica species group is described. This species is morphologically closely related to G. indica Hirst, 1917 but differs in the presence of 14 setae on the transversely elongated propodonotal shield and spur-like palp femoral setae dF and in the presence of leg setae vFIV and vTIV. Species of the genus Geckobia are recorded on hosts of the infraorder Iguania for the first time.

    ABSTRACT: Two new species of the feather mite genus Promegninia Gaud & Atyeo, 1967 (Avenzoariidae: Bonnetellinae) are described from procellariids in the northeasterm Atlantic Ocean: Promegninia bulweriae n. sp. from the Bulwer's petrel Bulweria bulwerii (Jardine & Selby) and P. calonectris n. sp. from the Cory's shearwater Calonectris borealis (Cory) (Procellariiformes: Procellariidae). Males of P bulweriae n. sp. are most clearly distinguished from the other known species in the genus by having short legs III extending only to the level of lobar apices and short conical tarsi III with lanceolate ventral seta w; females of this species are characterised by the absence of additional sclerites at postero-lateral angles of the prodorsal shield. Males of P. calonectris differ from the other known species in having bidentate terminal lamellae on the lobar apices and the entire adanal shield; females of this species are distinguished by having well-developed pygidial shields and a hysteronotal shield encompassing the bases of setae c2. Sequence data of the mitochondrial cytochrome c oxidase subunit I gene fragment (COI) are also obtained for the new species. An updated diagnosis of Promegninia and a key to the known species are provided.

    ABSTRACT: Species of Echinostoma Rudolphi, 1809 (Digenea: Echinostomatidae) belonging to the 'revolutum' species complex were re-examined based on material gathered in an extensive sampling programme in eight countries in Europe. The morphology of the life-cycle stages was studied in naturally and experimentally infected snail and bird hosts. A review, with an updated synonymy, is presented for six European species, including one new to science, i.e. Echinostoma revolutum (Frölich, 1802) (sensu stricto) (type-species), E. bolschewense (Kotova, 1939), E. miyagawai Ishii, 1932, E. nasincovae n. sp., E. paraulum Dietz, 1909 and Echinostoma sp. IG), and keys to the identification of their cercariae and adults are provided.

    ABSTRACT: Euparyphium capitaneum Dietz, 1909, the type-species of the genus Euparyphium Dietz, 1909, is described on the basis of material collected from the type-host Anhinga anhinga (L.) from Pascagoula River, which drains into the northern coast of the Gulf of Mexico. Combination of light and scanning electron microscopy observations of freshly collected and properly fixed specimens in our study has allowed us to provide novel information on the morphology and topology of the reproductive systems and other morphological features of the species. A Bayesian inference analysis based on the newly-obtained partial sequence of the nuclear 28S rRNA gene for E. capitaneum and 24 previously published sequences from the superfamily Echinostomatoidea Looss, 1899 provided evidence supporting the distinct status of the genera Euparyphium and Isthmiophora Lühe, 1909.

    ABSTRACT: Our helminthological examination of murid rodents on Luzon Island, Philippines, revealed a remarkable diversity of Hymenolepis Weinland, 1858. Here we describe two new species based on specimens from murid rodents Rattus everetti (Günther) and Apomys datae (Meyer) collected from Luzon Island. Hymenolepis alterna n. sp. differs from all known species of Hymenolepis in having irregularly alternating genital pores. This feature has not been reported from any previously known member of Hymenolepis. Additionally, Hymenolepis alterna n. sp. also differs from other Hymenolepis spp. in the relative position of both poral and antiporal dorsal osmoregulatory canals which are shifted towards the middle of the proglottis in relation to the ventral canals on both sides of the proglottides, and in having curved or twisted external seminal vesicle, covered externally by a dense layer of intensely stained cells. Hymenolepis bilaterala n. sp. differs from all known species of Hymenolepis in the relative position of both poral and antiporal dorsal osmoregulatory canals, which are shifted bilaterally towards the margins of proglottides in relation to the ventral canals, and in possession of testes situated in a triangle and eggs with very thin outer coat. A total of seven species of Hymenolepis are known from the Philippine archipelago. This total includes the cosmopolitan species Hymenolepis diminuta (Rudolphi, 1819), which was likely introduced to the island with invasive rats. Strikingly, all seven known species occur on the island of Luzon alone. By comparison, only six Hymenolepis spp. are known from the whole Palaearctic and seven from the Nearctic despite a much better level of knowledge of rodent helminths in these zoogeographical regions, as well as vast territories, diverse landscapes and very rich rodent fauna. This suggests that Hymenolepis spp. may have undergone an unusually active radiation in the Philippines. Possible explanations of this phenomenon are discussed.
